Abstract
A fuel recirculation system is provided that includes a fuel tank, a fuel delivery circuit for transporting fuel between the fuel tank and an internal combustion engine, a fuel recirculation circuit coupled with the fuel delivery circuit upstream of the engine and adapted for recirculating the fuel back to the fuel tank periodically. The present fuel recirculation system also includes a fuel pump, the capacity of which is sufficient to supply the required fuel to the engine via the fuel delivery circuit and recirculate the remaining volume of fuel by way of the fuel recirculation circuit periodically (e.g. once every 24 hours).
